Practice: Which of the following compounds will have the highest boiling point?
The Colligative Properties explain what happens to a pure solvent as it transitions to a solution.
The 4 Colligative Properties help to explain what happens to a pure solvent as solute is added to it.
Concept #1: The 4 Colligative Properties
Some Colligative Properties will increase and others will decrease with the addition of solute to a pure solvent.
Example #1: Pure benzene, C6H6, has a boiling point of 80.1ºC. What is a possible new boiling point once an unknown amount of glucose is added to the benzene solvent?
Concept #2: Van't Hoff Factor
Example #2: Which of the following compounds will have the largest value for the Van’t Hoff factor?
Concept #3: Solute Amount
Example #3: What is the ionic molality of potassium ions in 1.18 m solution of K3PO4?
